GRAlNlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 746,684, dated December 15, 1903. Application filed July 20, 1903. Serial No. 166,266. (No model.)

1'0 41% whom it may concern.-

Be it known that I, MICHAEL J. DAVIS, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Graining- Tools, of which the following is a specification.

The invention designs to provide a simple tool provided with patterns whereby grainin g of widely-different varieties may be quickly and neatly donethat is, a single tool which has all the patterns necessary in ordinary work of this character, thus avoiding the inconvenience and loss of time resulting rom the use of a plurality of tools necessary in simulating grains of difierent characters.

The invention consists in the novel tool hereinafter set forth, and more particularly defined by claims at the conclusion hereof.

In the drawings, Figure 1 is an elevation of the improved tool as seen from one side. Fig. 2 is a similar view from the other side. Fig. 3 is a central transverse section.

The body of the tool consists of a soft flexible piece of cylindrical tubing A, having open ends and usually made of a single thickness of soft rubber or like material. The periphcry of the tube is divided into longitudinal sections a, b, and 0, each having a different pattern thereon. Section ahas formed thereon a series of concentric semicircular ribs a, designed to grain asurface to simulate growths of all kinds of wood. In using the tool to produce such design one end of section ais pressed against the surface to be grained, and the tube is then drawn over said surface and slowly rotated to bring different portions of the-semicircular ribs against said surface. By variation of pressure and rapidity of rotation and reverse rotation of section a growths of difierent species and widely diiferent in design can be readily simulated.

Section I) is formed with a'series of short parallel transverse ribs 5, and section 0 is also formed with a series of parallel transverse ribs 0 somewhat wider than ribs I). Said ribs are designed to mark a surface in simulation of fine and coarse grained wood and wood of different species and commonly known as combing. Longitudinal grooves 11 extend from end to end of the body and are formed between the sections to slightly separate the is to be used the tube portions, located approximately at ninety degrees from said section, can be pressed together, as shown on dotted lines, Fig. 3, so the portions adjacent said section will be more nearly at right angles to said section. The tube being made of soft flexible material can also be bent longitudinally so the tool can be applied in recessesand grooves when desired. The pattern for combing being placed on the same body with the design for simulating growths can be quickly and almost continuously applied when a combination of designs is desired.

The improved tool possesses several important advantages. The tool suffices for graining where in manyinstanoes heretofore a plurality of tools with difierent patterns were necessary. Quicker Work is possible, because by mere rotation of the tool the different patterns may be brought into position for application. Each of the patterns can be applied Without danger of applying the adjacent pattern. By employing a pattern consisting of semicircular ribs in lieu of the circular ribs now in common use it becomes possible to extend the ribs around more than one-half of the peripheral surface of the tube, so a longer rotative stroke is possible without increasing the diameter of tube or roll.

What I claim as new, and desire to secure by Letters Patent, is

l. A graining-too], having a tubular body of flexible material, and divided into longitudinal sections, extending across the width of said body, the sections having different patterns for graining of diiferent varieties.

2. A graining-tool, having a tubular body of flexible material, and divided into longitudinal sections, extending across the width of said body, the sections having different patterns for graining of different varieties, the

body having longitudinal grooves between the sections.

3. A graining-tool having a tubular body of flexible material, and divided into sections extending from end to end of said body one lines, for application of one of the patterns of the sections having a pattern for simulatonly. ing different growths of Wood, and another of the sections having a pattern for comb- MICHAEL V 5 ing,the body having grooves extending from In presence ofend to end between the sections to render FRED GERLACH,
